Description
Technical field
The invention belongs to radio signal transmission field, particularly relate to a kind of antenna.
Background technology
Present mobile phone develops into the total multi mode terminal of present 2G, 3G and 4G from 2G simple in the past, and so just require that the frequency band debugging antenna is wider, the debugging area that antenna needs and space can be larger.But the trend of mobile phone does thinner and thinner now, and require metal edge frame, these are all unfavorable for the radiation of antenna, and be subject to the restriction in interior of mobile phone space, antenna is difficult to accomplish than preferably index, mostly there is high frequency (frequency band of more than 1.6G) and low frequency (frequency band of below 1G) difficulty is taken into account or is difficult to meet the demand of some frequency bands simultaneously.
Now the antenna of multi mode terminal is generally adopted in two ways: (1) high and low frequency uses same antenna body, high and low frequency has public signal transmssion line (namely adopting common signal access point), so only needs an antenna space; (2) high and low frequency uses two antenna bodies be separated, and high and low frequency signal does not use common signal line, needs two antenna spaces like this.The antenna requisite space of mode (1) is few, but antenna adjustment is difficult to take into account high and low frequency simultaneously.Mode (2) employs two antenna spaces and is separated by high and low frequency, can take into account high and low frequency so simultaneously, but when the limited space of interior of mobile phone, very difficultly can reserve two positions for debugging antenna.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of antenna, is intended to requisite space little and can take into account the transmission quality of high-frequency signal and the transmission quality of low frequency signal simultaneously.
The present invention is achieved in that a kind of antenna, is used in need and launches and in the electronic equipment that receives radio signals.This electronic equipment comprises a printed circuit board (PCB) and a ground plane.This printed circuit board (PCB) is provided with a test lead.This ground plane is positioned on this printed circuit board (PCB).This antenna comprises an antenna body and a switch modulation demodulator.This antenna body is positioned on this ground plane, and keeps at a certain distance away with this ground plane.This switch modulation demodulator is connected electrically between this printed circuit board (PCB) and this antenna body, and comprises first input end, the second input and output.This antenna body is provided with a low frequency signal access point and a high-frequency signal access point.This low frequency signal access point extends a wire and is electrically connected with this first input end by this antenna body.This high-frequency signal access point extends a wire and is electrically connected with this second input by this antenna body.This test lead is electrically connected with this output.When this first input end is electrically connected with this output by this switch modulation demodulator, form a low frequency signal antenna.When this second input is electrically connected with this output by this switch modulation demodulator, form a high-frequency signal antenna.
Compared with prior art, beneficial effect is in the present invention: this antenna requisite space is little and can take into account the transmission quality of low frequency signal and the transmission quality of high-frequency signal simultaneously.
